EYEG LASS-FRAIVI E.

SPECIFICATION forming part of Letters Patent No. 238,632, dated March 8,1881.

Application filed December 1, 1880. (ModeL) To all whom it may concern:

Be it known that I, LoU1s BAUM, a citizen of the United States, residingat Washington city, in the District of Columbia, have invented new anduseful Improvements in Eyeglasses, of which the following is aspecification.

The object of my invention is to provide eyeglasses with frames andnose-pieces which will not conduct heat or be liable to fracture fromaccidental knocks or falls, and to secure durability and simplicity andeconomy in the manufacture of eyeglass-frames.

It consists in a double eyeglass-frame made of leather, and having itsinner edges grooved to receive and retain the edges of the glasses, therespective frames having nose pieces formed in one piece therewith, andprovided with passages to embrace the spring and hold it in properposition. The elasticity of the leather causes the walls of the passagesfor the spring to press snugly against said spring and hold it fromslipping, and the nose-pieces yield and conform themselves to the shapeand size of the nose, and by their flexibility are, prevented from beingbroken by the strain of the spring.

In the accompanying drawings, Figure l is a view of an eyeglass havingits frames and nose-pieces made of leather, each frame and nose-piecebeing formed in one piece. Fig. 2 is a transverse section of one of theframes. Fig. 3 is a view of a blank for a frame and nose-piece cut fromleather.

The letter A indicates the frames of the glasses, and B the nose-pieces,connected at their backs to said frames, and having passages formedthrough them for the legs a of the spring-bridge 0, these legs beingcurved under the frames and having their tips preferably bearingslightly against said frames. The passages through the nose-pieces areof such size as to closely hug the legs of the spring and prevent theiraccidental withdrawal. The curves of the legs also assist in preventingtheir withdrawal as they must be straightened out in order to slipthrough the passages.

In constructing my improved frame I first out a blank, similar to thatshown in Fig. 3, from leather, preferably light sole-leather, and then,with a suitable tool, trim down and round off its outer edges, exceptthe clamping-face of the nose-piece, which I corrugate transversely, asusual. In the inner edge of the frame I then form a groove, D, as shownin Fig. 2, to receive the edge of the glass.

The righ t-hand frameis formed with athum bpiece, E, and the left-handframe with a catch, F, to engage with the pin G when the frames arefolded together. These frames may be cut by patterns or with suitablestamps.

Though I have shown my improved frames applied only to eyeglasses, it isobvious that these leather frames may be applied also to spectacles, theframes being provided with suitable lugs for the attachments ofbingepieces for the bows.

The frames, after being suitably trimmed, are preferably treated with awater-proof dressing, in order that they may resist the action ofperspiration, and they may be colored to imitate tortoise-shell, bluedsteel, or anyother material.

What I claim is- As a new article of manufacture, a doubleeyeglass-frame made of leather and having its inner edges grooved toreceive and retain the edges of the glasses, the respective frameshaving nose-pieces formed in one piece there with, and provided withpassages to embrace the spring and hold it in proper position,substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

LOUIS BAUM.
